I am sorry I made a mistake the rectangle getting code should look like
this:

   m_cTopBorder.GetWindowRect(&rectArray[0]);
   ScreenToClient(&rectArray[0]);

   m_cLeftBorder.GetWindowRect(&rectArray[1]);
   ScreenToClient(&rectArray[1]);

   m_cRightBorder.GetWindowRect(&rectArray[2]);
   ScreenToClient(&rectArray[2]);

   m_cBottomBorder.GetWindowRect(&rectArray[3]);
   ScreenToClient(&rectArray[3]);

The menu modifing code should go in OnInitDialog. But if you remove SC_MOVE
menu from the system menu then you won't be able to move the dialog at all.

So if you really need to remove the SC_MOVE item then you will need to
change the way you do your move. Something like this:

void CSqBmpBkgdBorderDlg::OnLButtonDown(UINT nFlags, CPoint point)
{
   m_StartPoint = point;
   SetCapture();
   CDialog::OnLButtonDown(nFlags, point);
}

void CSqBmpBkgdBorderDlg::OnMouseMove(UINT nFlags, CPoint point)
{
   if (nFlags & MK_LBUTTON && m_StartPoint.x >= 0 && m_StartPoint.y >= 0)
   {
      CPoint Diff = point - m_StartPoint;

      CRect Rect;
      GetWindowRect(Rect);
      Rect.OffsetRect(Diff);

      SetWindowPos(NULL,Rect.left,Rect.top,Rect.Width(),Rect.Height(),SWP_NOZORDER);
   }

   CDialog::OnMouseMove(nFlags, point);
}

void CSqBmpBkgdBorderDlg::OnLButtonUp(UINT nFlags, CPoint point)
{
   ReleaseCapture();
   m_StartPoint.SetPoint(-1,-1);

   CDialog::OnLButtonUp(nFlags, point);
}

  I have started another small practice program, and I wanted to just get
the drag correctly written. And I have found that when the rectangles in
the
array are converted to Client. It is not possible to drag the dialog with
the right or bottom borders. But when they are "not" converted it seems to
work very well. The problem I was having is later when I modify the system
menu for the dialog and taskbar button. But here is the code so far. And
all
the code in each relevant function is copied below.

Also, where would the modify system menu code be written?

====
class CSqBmpBkgdBorderDlg -
private:
CRect rectArray[4];
====

BOOL CSqBmpBkgdBorderDlg::OnInitDialog()
{
CDialog::OnInitDialog();

// Set the icon for this dialog. The framework does this automatically
// when the application's main window is not a dialog
SetIcon(m_hIcon, TRUE); // Set big icon
SetIcon(m_hIcon, FALSE); // Set small icon

// TODO: Add extra initialization here

ModifyStyle(WS_CAPTION,0,SWP_DRAWFRAME); //removes caption bar
ModifyStyle(0,WS_SYSMENU); //activates system menu
SetWindowText("Any Text Here"); //sets taskbar button text

m_cTopBorder.GetWindowRect(&rectArray[0]);
// m_cTopBorder.ScreenToClient(&rectArray[0]);

m_cLeftBorder.GetWindowRect(&rectArray[1]);
// m_cLeftBorder.ScreenToClient(&rectArray[1]);

m_cRightBorder.GetWindowRect(&rectArray[2]);
// m_cRightBorder.ScreenToClient(&rectArray[2]);

m_cBottomBorder.GetWindowRect(&rectArray[3]);
// m_cBottomBorder.ScreenToClient(&rectArray[3]);

return TRUE; // return TRUE unless you set the focus to a control
}

BOOL CSqBmpBkgdBorderDlg::OnEraseBkgnd(CDC* pDC)
{
// TODO: Add your message handler code here and/or call default

CBitmap bmpBkgd;
CDC dcMem;

bmpBkgd.LoadBitmap(IDB_BACKGROUND);

dcMem.CreateCompatibleDC(pDC);
dcMem.SelectObject(&bmpBkgd);

CRect rect;
GetClientRect(&rect);

pDC->BitBlt(0, 0, rect.Width(), rect.Height(), &dcMem, 0, 0, SRCCOPY);

return true;
}

UINT CSqBmpBkgdBorderDlg::OnNcHitTest(CPoint point)
{
// TODO: Add your message handler code here and/or call default

CPoint ptClient(point);
 ScreenToClient(&ptClient);

for(int i = 0; i < 4; i++)
  {
   if(rectArray[i].PtInRect(ptClient))
      return HTCAPTION;
  }

return CDialog::OnNcHitTest(point);
}
